Lecture 7 Exercise 7 1. Explain what are the connection-oriented communication and the connectionless communication. Give some examples for each of the above two types of communications. 2. Describe concepts of delay, throughput, bit corruption (error), disordered packet, duplicate packet, lost packet, flow control and network congestion, respectively. 3. Professionals sometimes refer to a “knee” in the delay curve. To understand what they mean, plot the effective delay for values of utilization between 0 and 0.95. Explain why utilization of a network should not approach to 1. 4. Match the following to one of the ISO 7 layers: a. Route determination. b. Flow control. c. Provides reliable end-to-end transmission of entire message. d. Reassembly of data packets into a message. e. Provides format and code conversion services. f. Provides user services such as electronic mail and file transfer. g. Provides verification of login and logout. h. Mechanical, electrical, and functional interface. 5. Why does a stop-and-go protocol have especially low throughput over a satellite channel that operates at two megabits per second. How to improve throughput using different flow control method?
